Description

【0001】
【発明の属する技術分野】
本発明はコンバインにおける穀稈搬送装置に係り、詳しくは、穂先側掻込み搬送体の構造に関するものである。
【0002】
【従来の技術】
従来、コンバインの刈取脱穀作業は、クロ−ラ走行装置を備えた機体の前部に穀稈引起し装置a、刈刃装置b、掻込み装置cおよび扱深さ搬送装置dを搭載した前処理部eを架設し、機体の走行時において、穀稈引起し装置aで引き起こした穀稈の株元を刈刃装置bで切断した後に、刈取られた穀稈を掻込み装置cから扱深さ搬送装置を経て穀稈供給チェ−ンfに継送し、後続の脱穀部に刈取穀稈を供給するように構成されている。
【0003】
刈取穀稈の稈長に応じて扱深さを自動調節して継送する扱深さ搬送装置dは、搬送タインgを巻回して形成される穂先側搬送部hと、ガイドレ−ルに沿う搬送チェ−ンiを巻回して形成される株元側搬送部jをそれぞれ上下位置に離間して構成されており、刈取穀稈の稈長に応じた扱深さの自動調節で扱深さ搬送装置dの上下動を行い、掻込み装置cの搬送チェ−ンkを介して搬送される刈取穀稈の株元側が、扱深さ搬送装置dの搬送始端位置Xまで搬送された際には、該刈取穀稈の株元側を株元側搬送部jの搬送チェ−ンiで挾持継送し、かつ刈取穀稈の穂先側を、穂先側搬送部jの搬送タインgに継送させて、後続の穀稈供給チェ−ンfに刈取穀稈を継送するようになっている。
【0004】
そして、掻込み装置cから扱深さ搬送装置dに至る従来の継送構成では、掻込み装置cから扱深さ搬送装置dに至る間で刈取穀稈の穂先側を継送する掻込み搬送体m、nが扱深さ搬送装置dから独立して固定されているため、稈長の長短により刈取穀稈の穂先部と掻込み搬送体m、nとの位置関係が変化することによる搬送乱れを防止するために、掻込み搬送体m、nを二段(m1、m2、n1、n2)に設けることで、稈長に対応した掻込み動作を行うようにしていた。しかしながら、掻込み搬送体を二段に設けることは、前処理部の重量増大を招くと共に、構成部品の増加による製造コストの上昇をも招いていた。
【0005】
【発明が解決しようとする課題】
本発明は、前述したような不具合を解消するべく創案されたものであって、簡単な構成でありながら、掻込み装置から扱深さ搬送装置への穀稈の搬送を良好に行うと共に、さらには稈長の長短に対応して穀稈の良好な搬送をすることができるコンバインの穀稈搬送装置を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
上記目的を達成するために本発明が採用した技術手段は、株元側搬送部と穂先側搬送部とを有し、後方側を支点として上下回動する扱深さ搬送装置と、該扱深さ搬送装置の前方に傾斜状に設けられると共に該扱深さ搬送装置と一体的に上下動する穂先側掻込み搬送体とを設けたコンバインの穀稈搬送装置であって、該掻込み搬送体より所定間隔を存した下方位置において、穀稈が該掻込み搬送体の搬送経路Xと反対側、即ち掻込み搬送体の非作用側へ倒れないように保持案内する穀稈ガイドを設け、該穀稈ガイドを前記掻込み搬送体と一体的に上下動するように構成したことを特徴とするものである。
【0007】
好ましくは、前記穀稈ガイドは、側面視において該掻込み搬送体と略平行して延出しており、さらに、機体の幅方向左右に掻込み搬送体を設けると共に、左側掻込み搬送体の下方に設けた穀稈ガイドの搬送方向終端側と該株元側搬送部に設けた株元チェ−ンガイドの搬送方向始端側とは平面視において交差していることを特徴とする。
【0008】
好ましくは、前記穀稈ガイドは弾性部材から形成されており、該扱深さ搬送装置が所定位置より下がった時には、該穀稈ガイドが下方に位置する部材に当接することで変形するようにしたことを特徴とする。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態について図面に基いて詳細に説明する。図1はコンバインの前処理部の平面図、図2及び図3はコンバインの前処理部の側面図であり、クロ−ラ走行部1の上に搭載された機体2を備えた三条刈りのコンバインの機体前方には前処理部3が設けてある。前処理部3のフレ−ム3aには穀稈引起し装置4が立上り状に設けてあり、またフレ−ム3aの先端にはデバイダ5が設けてある。フレ−ム3aの後端側には刈刃装置6が設けてあり、デバイダ5で分草された穀稈を穀稈引起し装置4で引き起こした後、刈刃装置6により株元側を切断し、掻込み装置を介して扱深さ搬送装置7へ搬送され、穀稈供給チェ−ン16に継送され、図示しない脱穀部に搬送される。
【0010】
掻込み装置は、スタ−ホイ−ル8a、8b、8cと、掻込み搬送ベルト9a、9b、9cと、株元搬送チェ−ン10a、10bと、穂先側掻込み搬送体11a、11bとを有する。搬送ベルト9a、9b、9cはスタ−ホイ−ル8a、8b、8cと同軸状に軸支された駆動プ−リとその前方に配設した従動プ−リとの間に巻回されていると共に、複数の掻込みタイン90を所定間隔を存して突設してなる。スタ−ホイ−ル8a、8b、8cは刈取穀稈の株元を搬送すると共に、搬送ベルト9a、9b、9cは刈取穀稈の中間部を搬送する。株元搬送チェ−ン10a、10bは、該駆動プ−リの下位においてこれと同軸状に巻回すると共に、扱深さ搬送装置7の搬送始端部位まで延出しており、刈取穀稈の株元を搬送するようになっている。
【0011】
図4に拡大して示すように、掻込み搬送体11a、11bは複数の搬送タイン110を備えた回転体からなり、穀稈の穂先側を掻込み案内するようにしている。掻込み搬送体11a、11bは機体の幅方向左右に設けてあり、搬送タイン110の回動軌跡は、株元搬送チェ−ン10a、10bの搬送方向と略同一方向に延出しており、穀稈搬送方向に向かって(機体後方に向かって)漸次近接するように配設されている。
【0012】
各掻込み搬送体11a、11bの下方には穀稈ガイド12a、12bが掻込み搬送体11a、11bに一体的に設けてある。穀稈ガイド12a、12bは棒状部材であり、一端側を掻込み搬送体11a、11bの後方側に装着すると共に、掻込み搬送体11a、11bの搬送タイン110の回転軌跡(穀稈の搬送経路)に沿うようにして機体前方に向かって延出させてなり、他端を自由端としている。図2に示すように、穀稈ガイド12a、12bは掻込み搬送体11a、11bの下方に所定間隔を存して略平行状に延出しており、引き起こし装置4で起こされた稈が掻込み搬送体11a、11bの非作用側Y(掻込み搬送体11a、11bの搬送経路Xと反対側である搬送タイン110の回動軌跡の及ばない範囲)へ倒れないように保持案内する作用をする。
【0013】
扱深さ搬送装置7は、搬送タイン70を備えたベルト体を有する穂先側搬送部7aと、ガイド70aに沿う搬送チェ−ン70bを有する株元側搬送部7bとからなり、図示しない稈長検出機構で稈長が検出され、該検出信号によって扱深さ搬送装置7を刈取部の伝動軸17(扱深さ搬送装置7の後方側に位置している)を支点として上下回動するように構成されている。例えば、稈長が短い場合には扱深さ搬送装置7は前方側が下方に回動した深扱状態となる。
【0014】
図5に示すように、一側の掻込み搬送体11aは、穂先側搬送部7aの先端部上面に一体的に設けてあり、他側の掻込み搬送体11bは支持パイプ13を介して扱深さ搬送装置7に連結されており、掻込み搬送体11a、11bは扱深さ搬送装置7の前方に傾斜状に配設してあると共に、扱深さ搬送装置7と一体的に上下回動するようになっている。したがって、扱深さ調整による扱深さ搬送装置7の上下回動に連繋して掻込み搬送体11a、11bが一体に上下回動するので、従来のように穂先側掻込み搬送体を複数段に配設することなく、良好に穀稈を案内搬送することができる。
【0015】
さらに、掻込み搬送体11a、11bの下方には穀稈ガイド12a、12bが一体的に設けてあるので、掻込み搬送体11a、11bの上下回動に伴って穀稈ガイド12a、12bは掻込み搬送体11a、11bとの関係を維持しながら上下動して、穀稈が掻込み搬送体11a、11bの非作用側へ倒れることを防止し、良好に穀稈を案内する。
【0016】
穀稈ガイド12a、12bについて詳述すると、一端を掻込み搬送体11a、11bの後方側の下方に装着し、掻込み搬送体11a、11bによる掻込み動作を妨げないようにして、下方かつ後方へ折曲しながら螺旋状に延出し、掻込み搬送体11a、11bの作用面(搬送タイン110の回転軌跡)に略沿った形状で、かつ側面視において掻込み搬送体11a、11bと略平行状に前方へ延出している。機体進行方向における左側掻込み搬送体11bの穀稈ガイド12bは、株元搬送装部7bの株元チェ−ンガイド70aと交差させるように螺旋状に下方へ下げてある。
【0017】
穀稈ガイド12a、12bは弾性部材で形成されており、さらには前方端部が自由端であり、したがってガイド先端の変位をより小さな荷重で行うことができ、特別なストッパ−を別途設ける必要がなく、ガイド自体が永久変形することもない。図3に示すように、扱深さ搬送装置7が所定位置より下がった時には、穀稈ガイド12a、12bが下方に位置する部材に当接することで変形するので、扱深さ最深状態(搬送体下限位置)を大きく採ること、換言すれば扱深さ搬送装置7の上下の可動範囲を大きく採ることができる。
【0018】
図示のものでは、扱深さ搬送装置7が下方に回動した場合には、穀稈ガイド12aは掻込み搬送ベルト9aの上部カバ−14に当接し、穀稈ガイド12bは株元搬送チェ−ン10bのチェ−ンガイド(図示せず)を支持する支持フレ−ム15にそれぞれ当接することで変形する。もっとも、穀稈ガイド12a、12bが当接する部材はこれらには限定されず、要は、それに穀稈ガイドが当接することで穀稈ガイドが変形するものであればよい。
【0019】
このように構成された穀稈搬送装置において、図2に示すように扱深さ搬送装置7が上位にある場合(長稈の場合)には、穀稈ガイド12a、12bは穂先側掻込み搬送体11a、11bと略平行状であり、ガイド12a、12bに沿って穀稈が移動する。図示しない扱深さセンサの検知によって扱深さ搬送装置7が下方に回動した場合には、扱深さ搬送装置7と一体である掻込み搬送体11a、11bが下方に移動し、さらに掻込み搬送体11a、11bと一体である穀稈ガイド12a、12bも下方に移動する。この過程においても、穀稈ガイド12a、12bは掻込み搬送体11a、11bと側面視平行状に延出している。
【0020】
さらに、扱深さ搬送装置7が下方に回動すると、穀稈ガイド12a、12bの前方側端部が掻込み搬送ベルトの上部カバ−14、支持フレ−ム15にそれぞれ当接するが、穀稈ガイド12a、12bは棒状のバネ材から構成されているので、穀稈ガイド12a、12bがさらに変形することにより、扱深さ搬送装置7はさらに下方に回動することができる。
【0021】
【発明の効果】
請求項1及び2に記載したものでは、穂先側掻込み搬送体より所定間隔を存した下方位置において、穀稈が該掻込み搬送体の搬送経路と反対側、即ち掻込み搬送体の非作用側へ倒れないように保持案内する穀稈ガイドを設け、該穀稈ガイドを前記掻込み搬送体と一体的に上下動するように構成したので、該穀稈ガイドが引き起こされた穀稈の姿勢を保持し、該穀稈が穂先側掻込み搬送体が作用しない側へ倒れるのを規制することができる。しかも、穀稈ガイドは掻込み搬送体に一体的に設けてあるので、掻込み搬送体との位置関係を維持した状態で上下動することができ、穂先遅れ等により掻込み搬送体に掛かり損ねる穀稈が生じて搬送乱れが起きることを可及的に防止することができ、刈取穀稈の整然な搬送を可能とする。
【0022】
請求項3に記載したものでは、掻込み部から扱深さ搬送装置への継送を円滑に行うことができ、もって掻込み部から株元搬送チェ−ンまでの穀稈の搬送を円滑かつ良好に行うことができる。
【0023】
請求項4に記載したものでは、穀稈ガイドは弾性部材から形成されており、該扱深さ搬送装置が所定位置より下がった時には、該穀稈ガイドが下方に位置する部材に当接することで変形するので、扱深さ搬送装置の上下可動範囲(特に下方への移動)を大きく採ることができる。

[0010]
The stirrer includes a star wheel 8a, 8b, 8c, a stir transport belt 9a, 9b, 9c, a stock transport chain 10a, 10b, and a tip side stap transport body 11a, 11b. Have. The conveyor belts 9a, 9b, and 9c are wound between a drive pulley that is coaxially supported by the star wheels 8a, 8b, and 8c and a driven pulley disposed in front of the drive pulley. At the same time, a plurality of scraping tines 90 are provided at predetermined intervals. The star wheels 8a, 8b and 8c convey the stock of the harvested cereal meal, and the conveyor belts 9a, 9b and 9c convey the intermediate part of the harvested grain meal. The stock transport chains 10a and 10b are wound coaxially with the lower part of the drive pulley and extend to the transport start end portion of the handling depth transport device 7. The original is to be transported.
[0011]
As shown in an enlarged view in FIG. 4, the scooping transport bodies 11a and 11b are composed of a rotating body having a plurality of transporting tines 110, and scrambling and guiding the head side of the cereal. The drive-in transport bodies 11a and 11b are provided on the left and right in the width direction of the machine body, and the rotation trajectory of the transport tine 110 extends in substantially the same direction as the transport direction of the stock transport chains 10a and 10b. It is arrange | positioned so that it may approach gradually gradually toward the coffin conveyance direction (toward the body back).
[0012]
Below the scooping transport bodies 11a, 11b, the grain guides 12a, 12b are provided integrally with the scooping transport bodies 11a, 11b. The cereal guides 12a and 12b are rod-shaped members, one end of which is attached to the rear side of the scooping transport bodies 11a and 11b, and the rotation trajectory of the transporting tine 110 of the scooping transport bodies 11a and 11b (the transport path of the cereals) X ) is extended toward the front of the machine body, and the other end is a free end. As shown in FIG. 2, the grain stalk guides 12a and 12b extend substantially parallel to each other at a predetermined interval below the stirrers 11a and 11b. It acts to hold and guide the carrier 11a, 11b so that it does not fall over to the non-operating side Y (the range that does not reach the rotation trajectory of the carrier tine 110 on the side opposite to the conveyance path X of the scraping carrier 11a, 11b ). .
[0013]
The handling depth conveying device 7 includes a tip side conveying portion 7a having a belt body having a conveying tine 70 and a stock-side conveying portion 7b having a conveying chain 70b along the guide 70a, and detects a cocoon length not shown. The length of the hook is detected by the mechanism, and the handling depth conveying device 7 is configured to rotate up and down based on the transmission shaft 17 (located on the rear side of the handling depth conveying device 7) of the cutting unit based on the detection signal. Has been. For example, when the saddle length is short, the handling depth conveying device 7 is in a deep handling state in which the front side is rotated downward.
[0014]
As shown in FIG. 5, one side of the scooping transport body 11 a is integrally provided on the top surface of the tip of the tip side transporting section 7 a, and the other side of the scooping transporting body 11 b is handled via the support pipe 13. It is connected to the depth conveying device 7, and the scraped conveying bodies 11 a and 11 b are arranged in an inclined shape in front of the handling depth conveying device 7 and rotate up and down integrally with the handling depth conveying device 7. It comes to move. Therefore, since the picking-up conveyance bodies 11a and 11b are integrally rotated up and down in linkage with the vertical rotation of the handling depth conveying device 7 by the adjustment of the handling depth, a plurality of stages of the scissors conveying arrangement on the tip side are conventionally provided. It is possible to satisfactorily convey and convey the cereal without being disposed on the surface.
[0015]
Furthermore, since the culm guides 12a and 12b are integrally provided below the scooping conveyance bodies 11a and 11b, the culm guides 12a and 12b are scraped along with the vertical rotation of the scrambling transport bodies 11a and 11b. It moves up and down while maintaining the relationship with the nest transporters 11a and 11b, preventing the cereals from falling to the non-working side Y of the stirrers 11a and 11b, and guiding the culm well.
[0016]
The cereal guides 12a and 12b will be described in detail. One end is attached to the lower side of the rear side of the scooping transport bodies 11a and 11b, and the rear side and the rear side are not hindered by the scooping operation by the scooping transport bodies 11a and 11b. It extends in a spiral shape while being bent to a shape substantially along the action surface (rotation trajectory of the transport tine 110) of the scooping transport bodies 11a and 11b, and substantially parallel to the scooping transport bodies 11a and 11b in a side view. It extends forward in a shape. The culm guide 12b of the left rake transporter 11b in the machine body traveling direction is lowered downward spirally so as to intersect with the stock chain guide 70a of the stock transport unit 7b.
[0017]
The cereal guides 12a and 12b are formed of an elastic member, and the front end is a free end. Therefore, the guide tip can be displaced with a smaller load, and it is necessary to provide a special stopper separately. In addition, the guide itself is not permanently deformed. As shown in FIG. 3, when the handling depth conveying device 7 is lowered from a predetermined position, the culm guides 12a and 12b are deformed by coming into contact with members located below, so that the handling depth is the deepest state (conveying body The lower limit position) can be increased, in other words, the upper and lower movable ranges of the handling depth conveying device 7 can be increased.
[0018]
In the illustrated example, when the handling depth conveying device 7 is rotated downward, the culm guide 12a comes into contact with the upper cover 14 of the stir-conveying belt 9a, and the culm guide 12b is connected to the stock transport chain. The frame 10b is deformed by coming into contact with the support frames 15 that support a chain guide (not shown). However, the member with which the culm guides 12a and 12b abut is not limited to these, and the point is that the culm guide may be deformed when the culm guide abuts against it.
[0019]
In the corn straw transporting device configured as described above, when the handling depth transport device 7 is at the upper position (in the case of a long cocoon) as shown in FIG. 2, the corn straw guides 12a and 12b are fed by the tip side. It is substantially parallel to the bodies 11a, 11b, and the cereals move along the guides 12a, 12b. When the handling depth conveying device 7 is rotated downward by detection of a handling depth sensor (not shown), the stiffening conveying bodies 11a and 11b integrated with the handling depth conveying device 7 move downward, and further The culm guides 12a and 12b that are integral with the embedded transporters 11a and 11b also move downward. In this process as well, the culm guides 12a and 12b extend in parallel with the drive-in carriers 11a and 11b in a side view.
[0020]
Further, when the handling depth conveying device 7 rotates downward, the front side ends of the culm guides 12a and 12b come into contact with the upper cover 14 and the support frame 15 of the rake conveying belt, respectively. Since the guides 12a and 12b are made of a rod-shaped spring material, the handling depth conveying device 7 can be further rotated downward by further deforming the cereal guides 12a and 12b.

【The invention's effect】
According to the first and second aspects of the present invention, at a lower position at a predetermined interval from the tip side scooping transport body, the cereal is opposite to the transport path of the scooping transport body, that is , the non-acting of the scooping transport body. Since the culm guide is held and guided so as not to fall to the side, and the culm guide is configured to move up and down integrally with the drive-in carrier, the posture of the culm in which the culm guide is caused , And the culm can be prevented from falling to the side on which the tip side scooping carrier does not act. Moreover, since the culm guide is provided integrally with the scooping transport body, it can move up and down while maintaining the positional relationship with the scooping transport body, and it will fail to catch on the scooping transport body due to a delay in the tip of the tip. It is possible to prevent as much as possible the occurrence of grain disturbance due to the occurrence of cereal grains, and to orderly convey the harvested grains.
[0022]
According to the third aspect of the present invention, it is possible to smoothly carry out the transfer from the scoring unit to the handling depth transporting device, thereby smoothly transporting the cereal from the scoring unit to the stock transport chain. It can be done well.
[0023]
According to a fourth aspect of the present invention, the culm guide is formed of an elastic member, and when the handling depth conveying device is lowered from a predetermined position, the culm guide abuts on a member positioned below. Since it is deformed, it is possible to increase the vertical movable range (especially downward movement) of the handling depth conveying device.
